Iodine-influenced morphological evolution of micrometer-sized poly(methyl methacrylate)-block-poly(vinyl acetate) particles upon hydrolysis

Iodine transfer polymerization was used to synthesize micrometer-sized block copolymer particles using methyl methacrylate (MMA) and vinyl acetate (VAc) in a microsuspension system. Three morphologies were obtained after hydrolysis, depending on the block ratio.
